A novel poly(ionic liquid) (PIL)-containing diblock copolymer was synthesized via a sequential living/controlled polymerization approach. First, the ring-opening polymerization of epsilon-caprolactone (CL) was carried out to obtain a monohydroxyl-terminated PCL. The terminal hydroxyl group of the PCL chain was then exploited to react with carboxyl group of 2-(dodecylthiocarbonothioylthio)-2-methylpropanoic acid to obtain a trithiocarbonate-terminated PCL. Thereafter, such trithiocarbonate-terminated PCL was used to mediate the radical polymerization of tri-n-butyl-(4-vinylbenzyl) phosphoniumbis(trifluoromethane)sulfonamide (TBP+-TFSI-) to afford PIL diblock copolymers. Notably, the PIL diblock copolymers are capable of displaying self-assembly behavior in selective solvent (e.g., ethyl acetate). In the suspensions of ethyl acetate, the self-assembly generated the spherical micelles with the aggregates of P(TBP+-TFSI-) as the cores and with PCL blocks as the coronas. Such a self-assembly behavior was further employed to obtain epoxy thermoset with nanostructures. Owing to the introduction of fluorine-containing PIL diblock copolymer, the surface dewettability of the thermosets was significantly improved owing to the enrichment of P(TBP+-TFSI-) at the surface. The introduction of PIL microdomains in epoxy resulted that the dielectric constants of the materials were significantly enhanced. More importantly, the dielectric constants were temperature-dependent and can be further enhanced while the nanostructured thermosets were heated above the glass transition temperature of PIL blocks.

Background: Pyrazole derivatives have been reported to possess numerous pharmacological activities viz., anti-inflammatory, antipsychotic, etc. Our group has disclosed that pyrazole benzamides display potent antibacterial and anti-tubercular activities. Objective: Synthesis of new pyrazole acetamides which possess hydrazone group to be evaluated for antitubercular activity. Methods: The key intermediate 5-aminopyrazole was synthesized with the known procedure, which is then converted into chloroacetamide. This compound than resulted in hydrazine derivative and finally converted into aromatic hydrazones. All the compounds were screened for antitubercular activity. Result: All the synthesized compounds have been characterized by their spectral data obtained and subjected to anti-tubercular activity. Among all the twenty tested compounds, three compounds, 5a5, 5b5 and 5b7 have demonstrated MIC value of 3.12 mu g/mL against MTB H37Rv. Docking studies revealed important hydrogen bonding interactions with InhA. Conclusion: Three compounds 5a5, 5b5 and 5b7 were found to be most potent among the series of compounds. Docking studies of compounds explained the presence of hydrogen bonding and pp stacking interactions with InhA. Further synthesis of more such derivatives with optimized groups would produce compounds with more potent anti-tubercular activity.

6-Formylisoophiopogonone B (7a) and 8-formylophiopogonone B (7b), two natural products isolated from Ophiopogon japonicus, represent a subgroup of rare 6/8-formyl/methyl-homoisoflavonoid skeletons. Herein we report an efficient method for the synthesis of these formyl/methyl-homoisoflavonoids. The synthesized compounds were evaluated for their neuroprotective effects on the MPP(+)induced SH-SYSY cell injury model and showed marked activity. Exploration of the neuroprotective mechanisms of compound 7b led to an increased expression of autophagy marker LC3-II and down-regulation of autophagy substrate p62/SQSTM1. Molecular docking studies showed that 7b may prevent the inhibition of the classic PI3K-AKT-mTOR signaling pathway by interfering with the human HSP90AA1.

The goal of this paper is the evaluation of fast two-dimensional gas chromatography applied to bio-oil samples. Bio-oils are complex matrixes that usually are analyzed by conventional gas chromatography, involving long columns, long time of analysis due to slow heating rates, and consequently, high cost associated to time consumed. Fast gas chromatography techniques are based on the use of narrow capillary columns that allow the achievement high-speed separations for complex samples, maintaining excellent resolution. Firstly, the two-dimensional gas chromatography method was optimized varying the heating rate (10, 15 and 20 degrees C min(-1)) and achieving the optimal separation at 15 degrees C min(-1). This method allies a good separation of bio-oil constituents with shorter time analysis. The developed method and the traditional conventional two-dimensional gas chromatography method (used in previous studies) were applied in the analysis of a mixture of 30 standard compounds. Despite coelutions of short retention time peaks (compounds with very similar physical-chemical properties), the fast two-dimensional gas chromatography method showed an increase in chromatographic signal and a noise reduction. Good results were also obtained in the real bio-oil sample. Fast two-dimensional gas chromatography maintained all the chromatographic information from conventional two-dimensional gas chromatography, reducing drastically the total time of analysis.

The chemical class of benzotrifluoride derivatives is widely used in active ingredients of various commercial products, such as pharmaceuticals, pesticides, herbicides, and crop protection agents. Past studies have shown that some benzotrifluorides are not stable under UV irradiation in water and convert into benzoic acids due to C-F bond hydrolysis. It was also observed, but never systematically studied, that the ring substituents play an important role on the direct photochemical reactivity of the CF3 moiety. In the present work, we explore the structure-reactivity relationship between ring substituent and direct photodefluorination for 16 different substituents, by determining fluoride production rates, quantum yields, and half-lives, and found that strong electron-donating groups enhance the reactivity toward hydrolysis. In addition, flufenamic acid, travoprost, dutasteride, cyflumetofen, flutoanil, and teriflunomide were also examined, finding that their direct photochemical reactivity could be qualitatively predicted based on their ring substituents. We provide here a tool to evaluate the environmental persistence of benzotrifluoride contaminants, as well as to design more photodegradable new active ingredients.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

An urgent yet challenging task is to overcome the limitations in substrate scope and regio- and chemoselectivity in the oxidative couplings between two arenes for the construction of unsymmetrical 2,2′-difunctional biaryls with diverse application requirements. In this work, a co-oxidant-free Rh(I)/Zn(NTf2)(2)/air catalytic system has been developed for dual chelation-assisted oxidative C-H/C-H cross-couplings between two anilines, between two phenols, and between phenols and anilines, which enables rapid assembly of rich libraries of 2,2′-bianilines, 2,2′-biphenols, and 2′-aminobiphenyl-2-ols. This protocol features air as the sole oxidant, complete regioselectivity, high chemoselectivity, low molar ratio of substrates (even 1:1), convenient operation, and scale-up synthesis. The established catalytic system is tolerant of the substrates having both electron-donating and electron-withdrawing substituents at different positions of the aryl ring. This work further discloses that the chemoselectivity of cross-coupling over homocoupling mainly relies on a suitable combination of two directing groups (i.e., a pair of strongly and weakly coordinating directing groups) rather than the electronically distinct properties between two substrates, which provides an inspiration for designing the matching directing group pair for the dual chelation-assisted oxidative Ar-H/Ar-H cross-couplings. Thus, this strategy allows the highly chemoselective cross-coupling between electronically similar coupling partners, which represents a challenging task in the oxidative Ar-H/Ar-H cross-coupling reactions.

Presently, artemisinin-based combination therapy (ACT) is the first-line therapy of Plasmodium falciparum malaria. With the emergence of malaria parasites that are resistant to ACT, alternative antimalarial therapies are urgently needed. In line with this, we designed and synthesised a series of novel N-(7chloroquinolin-4-yl)-N’-(4,6-diphenylpyrimidin-2-yl)alkanediamine hybrids (6a-7c) and evaluated their inhibitory activity against the NF54 chloroquine-susceptible strain as a promising class of antimalarial compounds. The antiplasmodial screening revealed that seven analogues showed promising to good activity with half-maximal inhibitory concentration ( IC50) = 0.32 mu Me4.30 mM. Compound 7a with 1,4-diamine butyl linker and 4-hydroxyl phenyl on fourth and sixth position of pyrimidine core showed the most prominent activity with an IC50 value of 0.32 +/- 0.06 mM, with a favourable safety profile of 9.79 to human kidney epithelial (HEK293) cells. The remaining six analogues showed moderate activity with IC50 values ranging from 7.50 mM to 83.01 mM. We further investigated the binding affinities of the molecules to two essential cytosolic P. falciparum heat shock protein 70 homologues; PfHsp70-1 and PfHsp70-z. Compound 7a exhibited the highest binding affinity for both PfHsp70s with K-D in a lower nanomolar range (4.4-11.4 nM). Furthermore, molecular docking revealed that compounds 6, 6k, 7b and 7a exhibited better fitness in PfHsp70-1 with compound 7a showing the highest and lowest binding scores of similar to 9.8 kcal/mol. Therefore, we speculate that PfHsp70-1 is one of the targets of these inhibitors. The bioisoteric replacement of the groups at phenyl ring at the fourth and sixth position of the pyrimidine core had a constructive association with antiplasmodial activity. The promising antiplasmodial activity of the synthesised analogues illustrates how crucial molecular hybridisation is as a strategy in the development of quinoline-pyrimidine hybrids as prospective antiprotozoal agents.
